- Abstract:
-
Aiming at the realistie need of shadow rendering, on the basis of the PCSS algorithm, this paperputs forward a solt shadow generation algorithm based on GPCPU. lt samples a region by poisson disk patterninstead of regular sampling mode, uses depth gradient to deal with the phenomenon of self-shadowing, uses theVSM algorithm to filter the shadow, and uses the summed area table to filter the shadow map dynamieally,which can improve the shadow qualily and rendering efficieney in a certain extent.
